This e-book deals with a collection of Longfellow's poems entitled "Birds of Passage: Flight the Fourth." The collection contains eight poems. The first deals with the U..S. Senator Charles Sumner, who was Longfellow's friend. In the second, Longfellow travels, not with his feet, but by reading about interesting places. The next three concern places in Italy: Cadenabbia on Lake Como, Monte Cassino, and Amalfi. The next discusses St. Francis of Assisi and his efforts to converse with birds. The final selection draws a lesson from the sleepy Songo River in Maine.
